Method for detecting static bending strength and elastic modulus of wood-based panels

Abstract

The invention belongs to the technical field of wood-based panels, and particularly relates to a method for detecting static bending strength and an elastic modulus of the wood-based panels. The method for detecting the static bending strength and the elastic modulus of the wood-based panels comprises the following steps of: intercepting a finished sample, conducting test by an electronic type tensile and compression testing machine, obtaining a detection result, confirming the detection result and checking the detection result. Through test by the electronic type tensile and compression testing machine, the corresponding amount of deformation, stress, bending moment, and the bending section modulus of the wood-based panels can be obtained; the static bending strength, and an average valueand a minimum value of the elastic modulus of the wood-based panels are obtained through unified calculation; and through the steps of intercepting the finished sample, conducting test by the electronic type tensile and compression testing machine, obtaining the detection result, confirming the detection result and checking the detection result and through repeatedly confirming of numerical values of the detection result and calculation, the effects of simultaneous detection of the static bending strength and the elastic modulus of the wood-based panels, a simple detection method and a relatively small error are achieved.

Description

technical field [0001] The invention belongs to the technical field of wood-based panels, and in particular relates to a detection method for static bending strength and elastic modulus of wood-based panels. Background technique [0002] The static bending strength is to determine the ratio of the bending moment and the bending section modulus of the specimen when the maximum load is applied; the general definition of the elastic modulus is: the stress in the unidirectional stress state divided by the strain in this direction. [0003] At present, the static bending strength and elastic modulus of wood-based panels need to be tested separately, resulting in low work efficiency. At the same time, the detection method is more cumbersome and complicated, and there are errors in the detected data, which affects the quality of wood-based panels. Therefore, There is an urgent need to develop a detection method for the static bending strength and elastic modulus of wood-based panel...
